The future of animal manures as fertilizer or wasteon of large amounts of slurry based on a policy of disposal or on nitrogen (N) use by crops will lead to the accumulation of phosphorus (P) in the surface soil and may result in the application of excessive amounts of potassium (K) with deleterious effects on crop quality and animal health.

Negative effects are apparent when they are larger than the positive effects or when the positive effects are masked. The paper deals with a selection of negative effects, mainly of cattle manure:.The paper gives possible ways to reduce the negative effects.

The Fundamental Subdivisions of EcologyThe effect of slurry treatments (storage, aeration, anaerobic digestion) on the N content and N forms in slurry, the N efficiency, the yield and the botanical composition of a sown meadow, is clearly lower than the effect of the kind (cattle or pig) and rate (50 or 100 m. ha. yr.) of the utilized slurries on the above mentioned parameters.
